CONVEYER- FLIGHT.

Application filed. May 7, 1923.

To all whom, it may come/Wt:

Be it known that we, LEONARD E. HUns'r and JAMES F. MILLER, citizens of the United States, and residents of Detroit, ll ayne (lounty Michigan, have invented a new and Improved Conveyer Flight. of which. the following is a specification.

This invention relates to conveyers and to the bearing blocks or shoes adapted to be attacl'ied to shafts and to the trunnions of conveyor flights and to other similar bodies, and its object is: to provide a conveyer flight and a bearing block of this character therefor which block may be readily reversed when one side or end becomes worn, which can be readily replaced, and which can be produced at low cost.

This invention consists of a conveyer flight having oppositely extending trunnions and a bearing block formed of two parts which have interengaging ridges or shoulders and which are grooved to fit shafts, trunnions or conveyer flights and similar devices, which parts are formed with transverse holes which are alined with a transverse hole in the shaft or trunnion on which the bearing block is mounted so that the block may be readily attached to the shaft or trunnion or removed therefrom without disturbing any other members attached to the shaft.

It further consists in a block of this char acter having flat bearing faces adapted to slide on rails or other guides to support the shaft or trunnion on which the block is mounted.

It also consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the accompanying drawing, Fig. 1 is an elevation of a conveyer flight whose trunnion is equipped with hearing collars embodying the present invention. Fig. 2 is a section on the line 2-2 thereof on. a larger scale. Fig. 3 is a plan and Fig. 4 is an end elevation of a conveyer-flight trunnion on which this improved collar is mounted.

Similar reference characters refer to like parts throughout the several views.

Fig. 1 is a cross section of a conveyer trough comprising a bottom 1, sides 2 in the form of channel bars on whose upper flanges the rails 3 are mounted. The conveyer flights 4 have the brackets 5 attached to their ends and to these brackets are con Serial No. 837,133.

nected the trunnions 6, preferably square in cross-section. Secured to the outer ends of these trunnions are the flight links 7 of the conveyer chain 8. and the supporting blocks 9. The trunnions 6 are shown aline d about cqui-distant between the longitudinal edges of the flight a so that it may be used to move bulk materials such as sand, coal, ashes. etc. in SLlPBlTlIIlPOSQCl troughs in opposite directions.

The blocks 9 are formed of two parts, 11 and 12. See Fig. The part 12 has a central tongue 13 provided with a longitudinal groove 14 to receive the trunnion 6 and the part 11 has a groove 15 to receive the tongue 13 and a second groove 16 to receive the trunnion. When the two parts are secured together and to the trunnion 6 by means of a bolt 17 which extends through registering holes in the trunnion and in the ridges in the two parts of the block, the block is substantially the equivalent of a solid. At the inner ends of these parts are the guide flanges 18 which prevent e-ndwise movement of the flight in the conveyer trough.

By having the joint in the block substantially parallel to the rail, the bolts 17 may be removed and the uppermost part of the block replaced without the necessity of lifting the chain and flights.

The details of construction and the proportions of the parts may all be changed by those skilled in the art without departing from the spirit of our invention. as set forth in the following claims.

We claim 1. A upporting block for conveyer chains comprising two parts having longitudinal interengaging ridges and registering grooves in their engaging faces to receive shafts or trunnions, and means to secure the parts together.

2. A supporting block comprising two parts having longitudinal interengaging ridges and registering grooves in their engaging faces to receive shafts or trunnions and means to secure the parts together comprising a bolt extending transversely through said parts of the block and through the interengaging ridges thereon and across the hole formed by the registering grooves.

3. A supporting block comprising two parts, one having a longitudinal groove and the other having a tongue to fit said groove, the grooved part being formed with a second groove in the bottom of the first and the other being formed] "ith a groove in the upper surface of said tongue to register with the second groove and to receive a shaft or trunnion.

4:. A supporting block comprising two parts having longitudinal interengaging ridges and registering grooves in their engaging faces to receive shafts or trunnions, and means to secure the parts together, said parts being formed with transverse guide flanges at one end of the block.

A conveyor flighteoinprising a plate and alined bars extending from opposite ends thereof, and bearing blocks rigidly but reinovably attached to said bars and having flat sides adapted to slide on supporting rails.

6. A conveyer flight comprising a plate and alined bars extending from opposite ends thereof, and bearing blocks rernovably attached to said bars and adapted to slide on supporting rails, said blocks being each formed of upper and lower interlocking parts and a bolt extending through the two parts and through the bar to secure the block in position.

7. A conveyor flight comprising a plate and alined bars extending from opposite ends thereof, and bearing blocks reinovably attached to said bars and adapted to slide on supporting rails, said bars being square in cross-section and said blocks being each formed of upper and lower interlocking parts to fit the bars and a bolt extending through the interlocking portions of the tvvo parts and through the bar to secure the block in position.

8. A conveyor flight comprising a plate and alined bars extending from opposite ends thereof, and bearing blocks reniovably attached to said has and adapted to slide on upporting rails, said blocks being formed 01" upper and lower parts, one having a groove to receive a tongue on the other part and the bottom of the groove of the first part and the top of the tongue of the second part being longitudinally grooved to receive one of the bars, said interlocking parts being formed with alined transverse holes to receive a bolt whereby said parts may be attached to the bar.
